In general I'm a fan of the freighter-style canoes. However, for the home in the 'burbs the john (or is it jon?) boat is probably best for the reasons stated above. For an apartment maybe you could look into a Sevylor or something similar. I am not sure if you can use compressed CO2 to inflate them. Just my two cents.
